When a small 2.0 g coin is placed at a radius of 5.0 cm on a horizontal turntable that makes three full revolutions in 3.14 s, the coin does not slip. What are?
(a) The coin's speed, the
(b) Magnitude and
(c) Direction (radially inward or outward) of the coin's acceleration, and the
(d) Magnitude and
(e) Direction (inward or outward) of the frictional force on the coin? The coin is on the verge of slipping if it is placed at a radius of 10 cm.
(f) What is the coefficient of static friction between coin and turntable?
